Latest update on China's aircraft carrier project

Chinese jet trains to take off using ski ramp.

The wonders of digital photography (on the ground and from commercial satellites) provide evidence that China is testing the use of its Su-30 aircraft and a ski ramp type carrier deck design. China is expected to have an operational carrier soon, and it will be one using a ski ramp (instead of a steam catapult). It was suspected that there was a ski ramp training facility somewhere, now it's been located, in Xian-Yanliang. What's strange about this is the altitude of this airbase; nearly 500 meters (rather than sea level.) Then again, Xian-Yanliang is a windy place, which allows testing of the stationary ski ramp built there, with winds typical of what would be encountered when the carrier turned into the wind for the commencement of aircraft launching operations.

Late last year, China announced that its first class of carrier aviators had begun training at the Dalian Naval Academy. The naval officers will undergo a four year course of instruction to turn them into fighter pilots capable of operating off a carrier. The Russians have warned China that it may take them a decade or more to develop the knowledge and skills needed to efficiently run an aircraft carrier. The Chinese are game, and are slogging forward.

Earlier this year, the Russian aircraft carrier Varyag was renamed the Shi Lang (after the Chinese general who took possession of Taiwan in 1681, the first time China ever paid any attention to the island) and given the pennant number 83. The Chinese have been refurbishing the Varyag, one of the Kuznetsov class that Russia began building in the 1980s, for several years now. It is expected to be ready for sea trials by the end of the year.

The Varyag has been tied up in a Chinese shipyard at Dailan since 2002. While the ship is under guard, it can be seen from a nearby highway. From that vantage point, local military and naval buffs have noted that some kind of work is being done on the ship. The only visible signs of this work are a new paint job (in the gray shade used by the Chinese navy) and ongoing work on the superstructure (particularly the tall island on the flight deck.) Many workers can be seen on the ship, and material is seen going into (new stuff) and out of (old stuff) the ship. The new contracts are believed to be for more equipment for the Varyag, in addition to the non-custom stuff already going into the ship.

Originally the Kuznetsovs were conceived of as 90,000 ton, nuclear powered ships, similar to American carriers (complete with steam catapults). Instead, because of the cost, and the complexity of modern (American style) carriers, the Russians were forced to scale back their goals, and ended up with the 65,000 ton (full load ) ships that lacked steam catapults, and used a ski jump type flight deck instead. Nuclear power was dropped, but the Kuznetsov class was still a formidable design. The thousand foot long carrier normally carries a dozen navalized Su-27s (called Su-33s), 14 Ka-27PL anti-submarine helicopters, two electronic warfare helicopters and two search and rescue helicopters. But the ship can carry up to 36 Su-33s and sixteen helicopters. The ship carries 2,500 tons of aviation fuel, allowing it to generate 500-1,000 aircraft and helicopter sorties. Crew size is 2,500 (or 3,000 with a full aircraft load.) Only two ships of this class exist; the original Kuznetsov, which is in Russian service, and the Varyag. Currently, the Kuznetsov is operating in the Mediterranean.

The Chinese have been in touch with Russian naval construction firms, and may have purchased plans and technology for equipment installed in the Kuznetsov. Some Chinese leaders have quipped about having a carrier by 2010 (this would have to be a refurbished Varyag). Even that would be an ambitious schedule, and the Chinese have been burned before when they tried to build new military technology in a hurry.
